a led reading pen

Abstract

The invention provides an LED reading pen, aiming at solving the problem in the prior art that the reading pen needs frequent charging or battery replacement. An LED reading pen, comprising a light-guiding shell, a fluorescent pen core, an LED point light source, a switch, and a power supply; the fluorescent pen core is arranged in the light-guiding shell and is a circular tube, and the light-guiding shell is provided with a reflection light channel, The reflected light channel is located in the fluorescent pen core; there are at least two LED point light sources and they are arranged on the light guide shell; each LED point light source is connected to a switch, and the switch makes one of the LED point light sources emit light or all the LED point sources The light sources emit light simultaneously. In the present invention, there is a fluorescent pen core, which can absorb the light emitted by the LED point light source. When the fluorescent pen core absorbs enough light, part of the LED point light source can be extinguished, which saves electric energy and increases the use time of the reading pen. , which solves the problem of frequent charging or battery replacement.

Description

technical field [0001] The invention relates to an LED reading pen. Background technique [0002] The reading pen is mainly composed of a micro camera, lighting system, decoding chip, memory chip, speaker, and identification module; it mainly recognizes graphics on printed matter to play pre-stored audio and video files. However, during the use of the current reading pen, the lighting system is always on, such as the electronic reading pen described in the application number 200920193786.8, which wastes electric energy and requires frequent charging or battery replacement, which affects the use time. Contents of the invention [0003] The invention provides an LED reading pen, aiming at solving the problem in the prior art that the reading pen needs frequent charging or battery replacement. [0004] In order to solve the above technical problems, the present invention is realized through the following technical solutions: an LED reading pen, including a light guide shell,...
